Gravity Powered Car

First, I Got four empty XS energy drink cans, two large, and two normal size. Then, I glued them together to form the base of the car. After that was done, I drilled holes into them for the axels. For the axels, I used two pencils. For the wheels, I used the tops of yogurt containers, two large, and two normal size. I inserted the axels into the body, then glued the wheels firmly to the axels. After that, I glued nine AA batteries to the bottom of the car for extra weight. When this was done, I covered the two front cans with plastic wrap. On top of the plastic wrap, I glued a bent piece of cardboard to make it more aerodynamic. Then I covered the open sides of the tip of the car with tin foil. After ths was done, I gave the wheels more friction with rubber bands. When all this was done, I decorated the car with fire and spray paint.

Fish Skin Alleles Lab Analysis

In the lab we saw how different alleles can help and organism or put them in harm's way. We also saw how environmental disasters and different environments can affect organisms. Specifically, the organisms were fish living in a lush and green stream. The green fish were able to camouflage into the seaweed and algae very well, so they avoided being eaten up by hungry predators. The orange and red fish were also able to pass unnoticed by predators. However, the yellow fish were extremely noticeable against the green environment and were found by bigger fish very quickly.


An Environmental Disaster

Despite the previous well being of the green skinned fish, the environment turned on it heals and a disaster occurred. Factory waste was dumped into the stream which killed all the seaweed and algae hence revealing the sand and rocks. The rocks and sand provided great camouflage for the yellow, orange, and red fish, but the green fish were not as lucky. Without the seaweed and algae, they had nothing to camouflage into, and therefore, no protection from predators. In effect, the alleles for green skin started to disappear and the alleles for red and yellow skin started to show up more.

Suggestions

If this lab were to be done again in the future, I would make it so that in addition to the yellow fish, the orange fish would also not be able to camouflage into the seaweed and algae. Also, I would give the yellow fish more alleles for means of defense (whatever that may be). These means of defense would only be able to protect the yellow fish 50% of the time. If the yellow fish were about to be put into the morgue, the student would flip a coin to determine whether the means of defense succeeds--heads it does, and tails it doesn't.

A Solid Discovery

Most of us think there are nine planets orbiting the sun, but there are others outside of the solar system called exoplanets. Over 500 of them have already been discovered, but recently, a more important one has been discovered. In Seattle during January, astronomers confirmed that the newly discovered planet is solid, unlike any of the others which are either unknown or made of gas. This planet is called Kepler-10b. It is 656 light years away, has a diameter 40% larger than the Earth's, and its mass is 4 times the Earth's. Kepler's orbit isery close to its star, so it is extremely hot, and cannot support liquid water, for it will evaporate. Astronomers found this planet by using the Heck telescope, which is located at the top of a dormant volcano in Hawaii. Astronomers are very excited about finding this planet in specific because it is the only one discovered so far that is solid like the Earth.

2011 Tech Trends

In 2011, many new gaming, communication, and transportation machine/devices will be gaining and losing popularity. Also, there might be yet another way to purchase merchandise. First, there is the electric car, which according to ABI research will most likely remain unused. This is because of the fear of driving too far away from a charging station and not being able to make it back home. Also, The radio and air conditioning can shorten battery life. Lastly, it is expensive from the beginning, and since it is new, auto dealers will mark the price up very much.

2011 will be a major year in the gaming world because each popular gaming companies are stepping it up a notch. Nintendo is coming out with the Nintendo 3Ds, a 3D version of the Nintendo DSi and possibly a new Wii! Sony has put in their part by coming out with the Playstation Move, and topping it off, the Kinect by Xbox.

When it comes to phones, the Apple iPhone and Android-based phones are leading. The sole reason the Android-based phones might be better is that the iPhone is flawed in security terms and cannot support some of the behind-the-firewall apps that are seen on the RIM platform.

Lastly, Mankind has used many items as money. We have also used credit and debit cards to substitute for our money. Now, some phone can accomplish many jobs with the help of applications. Guess what? Now, in 2011, we will be able to pay with our phones.
